Description

The present invention is a door handle set that combines a door handle provided as a handle on a sliding door or a hinged door that opens and closes the doorway of a room and a fitting for the door handle. Specifically, the door can be attached to the door in the field easily and quickly. Regarding the door handle set that reduces the work load of installation.

As a well-known door handle set, there is a set of a pair of door handles that face each other (in opposite directions) and are attached to both sides of the door. The door handle is usually provided with mounting portions extending at right angles to the longitudinal direction at both ends of the grip portion.

When attaching that type of door handle set to a door, first, as shown in FIG. 3 of the following Patent Document 1 as a prior art, among a pair of door handles arranged to face each other across the door. One is fixed to one side of the door with a countersunk bolt, along with a fixing collar provided between the door and the other door handle. The countersunk bolt penetrates the fixing collar and the door from the other side of the door and is screwed into the mounting portion of one of the door handles.

Next, a socket provided in the mounting portion of the other door handle is fitted to the outer periphery of the fixing collar, a set screw is passed through each of the three small holes provided in the peripheral wall of the socket, and the set screw is fixed. Screw it into the screw hole provided on the collar to fix the mounting part of the other door handle to the door.

The work of fixing the door handle mounting portion to the door is performed at the door installation site in consideration of improving the efficiency of door transportation. In the case of a door handle set that has mounting parts at both ends of the grip part of the door handle, two fixing collars, two countersunk bolts, and a total of six set screws are required to mount one set of door handle sets. Used. For this reason, in the field, it is necessary to tighten two countersunk bolts and six set screws for each door.

Further, in the fixing collar, the position of the screw hole provided in the fixing collar is matched with the position of the small hole provided in the mounting portion of the other door handle, and the countersunk bolt is held in that state. Until the door handle is fixed to the door, it is necessary to tighten it while preventing the fixed collar from rotating together, which is also troublesome.

In the door handle mounting structure proposed by Patent Document 1, a set screw having an annular groove having a tapered surface on the outer periphery of the fixed collar and screwed into the mounting portion of the other door handle (Patent Document 1 is locked). The other door handle is pulled toward the door and fixed by pressing the tapered surface of the annular groove (referred to as a screw).

In addition, there is a nut called a speed nut that can be engaged with a screw hole simply by inserting the bolt without rotating it. One of the speed nuts is a split nut that is entirely divided into a plurality of segments in the circumferential direction, and the split nut is inserted into a tapered hole and urged in a direction of reducing the diameter with a spring. .. Speed nuts of that type are shown, for example, in Patent Documents 2 and 3 below.

The present invention allows the use of the speed nut to allow easy and quick on-site installation of the door handle.

Japanese Unexamined Patent Publication No. 9-177383 Jikkenhei 4-81311A JP-A-2002-89532

In the door handle mounting structure proposed by Patent Document 1, a set screw for fixing the door handle, which is screwed into the mounting portion of the other door handle, is inserted into the annular groove on the outer periphery of the fixing collar fitted to the countersunk bolt. Since it is pressed against the tapered surface of the annular groove, it is not necessary to align the screwing position of the set screw with the position of the set screw pressing portion of the fixed collar.

However, for the door handle that fixes both ends of the grip, the work of passing two countersunk bolts through the door through the shaft hole and screwing it into the screw hole at the end of the other door handle, and one door It is indispensable to fix the mounting parts at both ends of the handle to the fixing collar with set screws, and it takes a lot of time and effort to mount the doors in the field, especially in a building with many doors.

In order to meet the demand for labor cost reduction, it is important to reduce the man-hours and time of field work, but the door handle, which has mounting parts at both ends of the grip part, is mounted on the door with two countersunk bolts and two. The mainstream method is to use one fixing collar and four set screws, and there is no one that can meet the demand for labor cost reduction.

The present invention has been made in view of the above-mentioned current technology, and provides a door handle set that can be easily and quickly mounted on a door in the field and that enables stable mounting without rattling. Is an issue.

In order to solve the above problems, in the present invention, the door is arranged so as to face each other across the door, and the door is inserted into a pair of door handles attached to both sides of the door and a shaft hole provided through the handle installation portion of the door. A mounting screw, a speed nut embedded in the mounting part of one door handle (a type of nut that is inserted and engaged without rotating the mounting screw), and a relative rotatable mounting on the outer circumference of the neck of the mounting screw. A plug (fixed collar referred to in Patent Document 1) that is inserted and fixed to a socket provided in the mounting portion of the other door handle, and a handle mounting portion of the plug and the door that is externally fitted and fixed to the mounting screw. Equipped with an adjustment nut placed between and
The mounting screw assembled together with the plug to the other door handle is passed through a shaft hole of the door and inserted into the speed nut embedded in the mounting portion of the one door handle.
Provided is a door handle set in which the adjusting nut is rotated until the door is pinched by the pair of door handles to tighten the mounting screws to attach the pair of door handles to the door. To do.

The door handle set can be considered in two forms, one in which the pair of door handles are connected and fixed with one mounting screw, and the other in which the pair of door handles are connected and fixed with two mounting screws.

In a door handle set that is connected and fixed with two mounting screws, the pair of door handles have mounting portions at both ends (the mounting location of the mounting portion is considered to be an end), and both ends of one door handle are considered. The speed nuts are individually embedded in the mounting portion, the mounting screws and the plug are provided in the mounting portions at both ends of the other door handle, and the plug is fixed to the mounting portion to install the door handle. The mounting screws are individually inserted into two shaft holes provided so as to penetrate the portions, and the mounting screws are fastened to the speed nuts of the mounting portions at both ends of one door handle.

The speed nut includes a casing having a tapered hole and fixed to a mounting portion of one door handle, and a plurality of nut segments inserted into the tapered hole of the casing at intervals in the circumferential direction. A well-known combination of a split nut and a spring that receives a reaction force from the casing and urges the split nut toward the smaller diameter side of the tapered hole can be adopted.

Alternatively, the speed nut includes a casing fixed to the mounting portion of one of the door handles, and a plate nut having a locking claw that enters the valley of the screw of the mounting screw at the edge of the hole through which the mounting screw is passed. It is also possible to adopt a leaf nut that is built in the casing and is held in a state where it cannot rotate relative to the casing and its axial movement is restricted. In this case, the speed nut includes a mooring washer having a check claw that engages with the outer periphery of the tip of the mounting screw at the edge of a hole through which the mounting screw is passed, and the mooring washer is incorporated in the casing in the axial direction. It is preferable that the movement is held in a regulated state.

Further, it is preferable to interpose a rubber packing that comes into contact with the door and a washer that abuts against the adjusting nut between the adjusting nut and the door. The rubber packing and washer can also be interposed between one door handle and the door.

The adjusting nut can be fixed to the mounting screw by using a stopper such as a spring pin.

In the door handle set of the present invention, the mounting screw, the adjusting nut, and the plug can be pre-assembled to the mounting portion of the other door handle. The pre-assembly work can be done at the factory before shipping the product.

Further, in the pre-assembly work, when the plug is fixed to the attachment portion of the other door handle with a set screw, the plug inserted into the receiving port of the other door handle is inserted into the screw hole provided in the plug. It can be rotated without any restrictions until the position coincides with the small hole through which the set screw on the receiving port side is passed.

The mounting screw provided on the other door handle is inserted into a shaft hole provided through the door at the door installation site, and the tip end side of the mounting screw penetrating the shaft hole is on the opposite side of the door. Insert it into the speed nut of the mounting part of one of the door handles that is in contact with the surface.

The insertion is performed until the adjusting nut fixed to the mounting screw is directly or indirectly pressed against the door. However, at this stage, the door handles attached to both sides of the door are not sufficiently fixed, and unavoidable backlash occurs in fastening.

The speed nut incorporates a split nut disclosed in Patent Documents 2 and 3 described above, and a plate nut having a locking claw that enters the valley of the screw of the mounting screw at the edge of the hole through which the mounting screw is passed. There is something. In fastening using the speed nut, after inserting the mounting screw into the speed nut, the mounting screw or speed nut is rotated in the tightening direction to absorb unavoidable backlash (play in the longitudinal direction of the bolt). However, the mounting screw whose head is inserted into the socket of the mounting portion of the other door handle is not allowed to rotate after being inserted into the speed nut.

Further, the speed nut embedded in the mounting portion of one of the door handles is not allowed to be rotated from the outside.

For this reason, it has not been considered inappropriate or impossible to use a speed nut for fixing the door handle.

The door handle set of the present invention enables the use of the speed nut by providing the adjusting nut.

After inserting the mounting screw attached to the other door handle into the speed nut provided in the mounting portion of one door handle, the adjustment nut is then operated to adjust the mounting screw to which the adjustment nut is fixed. Rotate with the nut in the tightening direction.

As a result, the mounting screw is screwed into the speed nut to eliminate the play that occurs between the mounting screw and the speed nut, and the door handle is fixed to the door without rattling.

In the on-site work at this time, the mounting screw provided on the mounting part of the other door handle is passed through the shaft hole of the door, inserted into the speed nut of the mounting part of one door handle, and fixed to the mounting screw. All you have to do is rotate the adjustment nut.

Therefore, it is not necessary to prevent the plug from rotating together, which has been conventionally performed, and the work is remarkably simplified. In addition, when the door handle rattles due to the so-called thinning of the door due to aging, it is troublesome to remove the set screw fixing the plug once, remove the other door handle, and re-tighten the mounting screw. However, the product of the present invention can eliminate rattling without any trouble by simply tightening the adjusting nut.

In addition, the door handle set including the rubber packing and the washer can prevent scratches on the surface of the door handle installation portion when the adjusting nut is rotated and prevent rattling after tightening the mounting screws.

The door handles are marked with additional symbols -1 and -2 to distinguish between the two.

Since one end and the other end of the door handles 2-1 and 2-2 have the same structure, only one end of the door handle is shown in FIGS. 2 to 4. Therefore, in FIGS. 2 to 4, only half of the mounting screws 3, the speed nut 4, the plug 5, the set screw 6, the adjusting nut 7, the rubber packing 8, the washer 9, the spring washer 10, and the flat washer 11 are shown. ing.

The door handles 2-1 and 2-2 are provided with mounting portions 2b extending in a direction perpendicular to the longitudinal direction of the grip portion 2a on both ends of the grip portion 2a (see FIG. 1). It is arranged so as to face each other across D, and is attached to both sides (one side and the other side) of the door D.

The illustrated door handles 2-1 and 2-2 are a combination of a solid shaft constituting the grip portion 2a and a pipe constituting the mounting portions 2b at both ends, but the whole is formed of a pipe. It may be a thing. Further, the mounting portion 2b may be provided in the middle of the longitudinal direction near both ends of the grip portion 2a.

The mounting screw 3 is inserted into the shaft hole H provided through the handle installation portion of the door D, and is inserted into the speed nut 4.

As shown in FIGS. 2 to 5, the exemplary speed nut 4 includes a casing 41 that is inserted inside the mounting portion 2b of one door handle 2-1 and fixed to the mounting portion 2b with a set screw 12. It is composed of a split nut 42 composed of the nut segments 42a, a spring 43 for urging the split nut 42 in one direction, and a spring receiving washer 45 attached to the casing 41 using a snap ring 44.

The casing 41 has a tapered hole 41a, and each nut segment 42a of the split nut 42 is inserted into the tapered hole 41a at intervals in the circumferential direction. Further, on the inner circumference of the tapered hole 41a, a guide portion 41b for guiding the axial movement of each nut segment 42a is formed between adjacent nut segments 42a. By the guide of the guide portion 41b, the split nut 42 expands in diameter when moving toward the large diameter side of the tapered hole 41a, and contracts in diameter when returning to the small diameter side of the tapered hole 41a.

The spring 43 receives a reaction force from the casing 41 and urges the split nut 42 toward the small diameter side of the tapered hole 41a.

The speed nut 4 is embedded in the mounting portions 2b at both ends of one of the door handles 2-1 with the small diameter side of the tapered hole 41a facing the insertion side of the mounting screw 3.

The plug 5 is mounted on the outer circumference of the neck of the mounting screw 3 so as to be relatively rotatable.

Further, the plug 5 is not limited to the cylindrical shape shown in the drawing, and a plug 5 that matches the cross-sectional shape of the receiving port 2c of the mounting portion 2b is used.

The illustrated plug 5 is provided with two screw holes 5a at positions symmetrical with respect to the center of the outer circumference, and a set screw 6 is screwed into the screw holes 5a. The plug 5 may be provided with an annular groove having a tapered surface as shown in Patent Document 1 described above, instead of the screw hole 5a.

The adjusting nut 7 is fixed to the outer circumference of the mounting screw 3 and is arranged between the plug 5 and the handle installation portion of the door D. The illustrated adjusting nut 7 has a substantially cylindrical rotation operation portion 7b provided with a chamfered portion 7a (see FIG. 4) having a width across flats for engaging a spanner on the outer circumference, and a cylinder provided on one surface of the rotation operation portion 7b. It has a shaped boss portion 7c. The rotation operation unit 7b is set to a thickness of about 3 mm in consideration of the influence on the appearance of the entire door handle set 1.

The boss portion 7c is inserted into a concave portion having a circular end face view provided on one surface of the plug 5. As a result, the adjusting nut 7 is positioned concentrically with the plug 5.

To fix the adjusting nut 7 to the mounting screw 3, as shown in FIG. 2, the spring pin 13 is press-fitted into the pin hole provided in the boss portion 7c of the adjusting nut 7, and the tip of the spring pin 13 is attached to the outer circumference of the mounting screw 3. This is done by engaging with the recess provided in. The spring pin 13 is driven into the pin hole of the boss portion 7c of the adjusting nut 7 from the position of the notch 5b (see FIG. 4) provided in the plug 5. The adjusting nut 7 can be fixed to the mounting screw 3 by providing a stopper other than the spring pin, for example, a key and a key groove.

The adjusting nut 7 may also be any as long as it can be rotated from the outside. Hexagon nuts for engaging spanners and cylindrical nuts with engaging portions such as pin holes for engaging hook wrenches on the outer circumference can also be used.

For the mounting screw 3 with the plug 5 mounted on the neck, the plug 5 is inserted into the socket 2c provided in the mounting portion 2b of the other door handle 2-2, and the plug 5 is fixed to the mounting portion 2b with the set screw 6. Assemble to the door handle 2-2. The work can be done at the factory before shipping the product.

To fix the plug 5 to the mounting portion 2b, as shown in FIG. 3, a small hole 2d for locking the set screw 6 is provided on the peripheral wall of the receiving port 2c of each mounting portion of the other door handle 2-2. It is provided so as to correspond to the screw hole 5a, and the set screw 6 is passed through the small hole 2d and screwed into the screw hole 5a of the plug 5 inserted into the receiving port 2c.

The rubber packing 8 is in contact with one surface and the other surface of the door D, and the washer 9 is in contact with the adjusting nut 7 adjacent to the rubber packing 8 and against the mounting portion 2b of one of the door handles 2-1. It is externally fitted to the mounting screw 3 at each position. The rubber packing 8 and the washer 9 contribute to prevent scratches on the surface of the handle mounting portion of the door D and prevent rattling after tightening the mounting screws 3, but they are not essential parts.

Next, the procedure for attaching the door handle set 1 of the first embodiment to the door D will be described.

The mounting screws 3 can be assembled to the mounting portions 2b at both ends of the other door handle 2-2 at the installation site of the door D, but if the mounting screws 3 are completed at the factory before shipping the product, the mounting screws 3 can be assembled at the site. Since the work man-hours are reduced, it is preferable here that the mounting screws 3 to which the plug 5 and the adjusting nut 7 are mounted and brought into close contact with each other are already assembled to the mounting portions 2b at both ends of the door handle 2-2.

At the site, one door handle 2-1 incorporating the speed nut 4 is applied to one surface of the handle installation portion of the door D, and the two mounting screws 3 assembled to the other door handle 2-2 are attached to the door D. It is inserted into the two shaft holes H provided in the handle installation portion from the other side at the same time.

Then, the tip end side of each mounting screw 3 penetrating the shaft hole H is inserted into the inside of the speed nut 4 incorporated in the mounting portions 2b at both ends of one door handle 2-1. By the operation, the tip side of the mounting screw 3 is inserted inside the split nut 42, the screw of the mounting screw 3 and the split nut 42 mesh with each other, and the adjusting nut 7 fixed to the mounting screw 3 passes through the washer 9 and the rubber packing 8. The temporary connection of both door handles 2-1 and 2-2 is completed when the door D is pressed against the other surface.

Therefore, this time, the adjusting nuts 7 fixed to the two mounting screws 3 are rotated in the tightening direction, and the mounting screws 3 that rotate together with the adjusting nuts 7 are embedded in one of the door handles 2-1. Screw it into the nut 4. As a result, the play generated between the mounting screw 3 and the split nut 42 is absorbed, and both door handles 2-1 and 2-2 sandwich the door D and are fixed to the door D without rattling.

In the door handle set 1 of the first embodiment, as described above, the door D can be operated only by inserting the mounting screw 3 assembled to the other door handle 2-2 and rotating the two adjusting nuts 7. Installation of door handles 2-1 and 2-2 on both sides of the door is completed.

Therefore, the labor and work time required for on-site installation are significantly reduced compared to the existing door handle set, and the cost increase due to the addition of the speed nut 4 and adjustment nut 7 can be offset by the reduction in labor costs. it can.

Even when the mounting screw 3 is assembled to the other door handle 2-2 in the field, the fixing work of the mounting screw 3 with the set screw 6 can be performed before passing the mounting screw 3 through the shaft hole H of the door D. Therefore, workability is improved as compared with the conventional product, labor can be reduced, and work time can be shortened.

In this door handle set 1, the set screw 6 is removed to separate the other door handle 2-2 from the plug 5, and then the exposed mounting screw 3 is rotated in the loosening direction and pulled out from the speed nut 4. As a result, the pair of door handles 2-1 and 2-2 fixed to each other can be removed from the door D and replaced as a whole.

FIG. 6 shows the door handle set 1 of the second embodiment of the present invention. The door handle set 1 of the first embodiment uses two mounting screws 3 to fix both ends of the pair of door handles 2-1 and 2-2 to the door D, but in this second embodiment, it is large. Door handles 2-1 and 2-2, which are intended for hinged doors and lightweight doors that are not subject to load or twisting force, are attached to the door D using one mounting screw 3.

The fastening and fixing portions of both door handles 2-1 and 2-2 by the one mounting screw 3 have the same structure as that of the first embodiment.

7 and 8 show the door handle set 1 of the third embodiment of the present invention. The door handle set 1 of the third embodiment is based on the one of the first embodiment, and the speed nut 4 is changed to a plate nut type, and the mounting screw 3 is also a small diameter portion having no screw on the tip side. It has been changed to one with 3a. The mounting screw 3 has a tip protrusion 3b having a smaller diameter than the small diameter portion 3a protruding from the end surface of the small diameter portion 3a so that the mounting screw 3 can be smoothly inserted into the speed nut 4.

As shown in FIG. 9, the plate nut type speed nut 4 used in the third embodiment is inserted inside the mounting portion 2b of one of the door handles 2-1 and has two spring pins 46. The casing 47 fixed by the casing 47, the plate nut 48 built in the casing 47, the push nut 49 as a mooring washer built in the casing 47 on the side farther from the door D than the plate nut 48, and the push nut 49. It is provided with a spring pin 50 that prevents the casing 47 from falling off.

The casing 47 has a substantially cylindrical shape that fits into the receiving port 2c of one door handle 2-1 and is opposite to the recess 47a for holding the plate nut 48 that opens to the side near the end surface on the door D side. A recess 47b for holding the push nut 49 is provided at the boundary between the end face and the side surface.

The plate nut 48 has a rectangular shape in a plan view, has a locking claw 48a that enters the valley of the screw of the mounting screw 3 at the edge of the hole through which the mounting screw 3 is passed, and has a recess 47a on the door D side of the casing 47. It is inserted into the casing 47 and is held in a state where it cannot rotate relative to the casing 47 and its axial movement is restricted. Then, when the mounting screw 3 is rotated in the tightening direction, it is attracted to the door D side in a state of being stopped by the casing 47 by the thrust acting on the screwed portion, and is pressed against the end wall of the casing 47 on the door D side. It has become.

That is, even in the door handle set 1 of the third embodiment, by rotating the mounting screw 3 in the tightening direction, the inevitable backlash at the initial stage of inserting the mounting screw 3 is absorbed and both door handles 2-1 and 2- The rattling of 2 can be eliminated.

Further, the push nut 49 has a check claw 49a that engages with the outer circumference of the small diameter portion 3a of the mounting screw 3 at the edge of the hole through which the mounting screw 3 is passed, and the recess 47b on the side far from the door D of the casing 47. It is inserted into and held in a regulated state of axial movement. Then, when the small diameter portion 3a of the mounting screw 3 is inserted, the reverse stop claw 49a bends in the diameter expansion direction to allow the insertion, and when the mounting screw 3 tries to move in the pulling direction, the reverse stop claw 49a Is designed to bite (strongly engage) with the outer circumference of the small diameter portion 3a of the mounting screw 3 to prevent the small diameter portion 3a from coming off.

Therefore, in order to facilitate the insertion work of the mounting screw 3 into the speed nut 4, even if the plate nut 48 is adopted so that the locking claw 48a is easily bent and the insertion resistance of the plate nut 48 is reduced, it can be used. The push nut 49 can make up for the lack of the retaining force (the force to prevent the mounting screw 3 from coming off) of the plate nut 48. That is, the push nut 49 enhances the reliability of preventing the door handles 2-1 and 2-2 from coming off.

Since the plate nut 48 and the push nut 49 incorporated in the speed nut 4 may be commercially available mass-produced products, the door handle set 1 is compared with the first embodiment in which the speed nut 4 provided with the split nut 42 described above is adopted. The overall cost can be reduced.

The door handle set 1 of the third embodiment can be totally replaced by the same procedure as that of the first embodiment. That is, by removing the set screw 6 and separating the other door handle 2-2 from the plug 5 and rotating the exposed mounting screw 3 in the loosening direction, the mounting screw 3 is driven by the thrust acting on the engaging portion of the plate nut 48. Since the screw to the plate nut 48 is released and the small diameter portion 3a of the mounting screw 3 is pulled out from the push nut 49, both door handles 2-1 and 2-2 can be removed from the door D.

Further, in the speed nut 4, instead of the plate nut 48 shown in FIGS. 7 to 9, a plate nut 51 having a circular shape in a plan view as shown in FIG. 10 can be used. The plate nut 51 also has a locking claw 51a that enters the valley of the screw of the mounting screw 3 at the edge of the hole through which the mounting screw 3 is passed. The plate nut 51 can also be incorporated as a mooring washer in place of the push nut 49.

As shown in FIGS. 7 and 8, it is better to use a mounting screw 3 having a small diameter portion 3a without a screw and a tip protrusion 3b in terms of ease of insertion into the speed nut 4 and prevention of disconnection. Although it is preferable, a commercially available product having no small diameter portion or tip protrusion can be used to reduce the cost.

Further, depending on the magnitude of the fastening force required for stable fixing of the door handle, it is conceivable to omit the mooring washer.

It should be considered that the embodiments disclosed this time are exemplary in all respects and not restrictive. The scope of the present invention is indicated by the scope of claims, not the above-mentioned meaning, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.

For example, in the embodiment, the set screw 6 is used to fix the plug 5 to the mounting portion 2b of the other door handle 2-2, but the plug may be fixed to the other door handle by other means. Good. Even if a door handle and a plug are inseparably fixed as the fixing means, the other door handle can be plugged, the mounting screw, and the other door handle by operating the adjusting nut and rotating the mounting screw in the loosening direction. It can be removed from the door integrally with the adjustment nut, and the entire door handle set can be replaced.
